Hi Guys,

I currently have a problem with an Actron 3 Phase R22 ducted unit.
Model:SRA22C-0300
The unit has an M series controller and is coming up with an E9 fault.
Which is High/ Low pressure fault.
After bridging out both HP and LP switch and letting the unit run to see if it faults out to rule out faulty outdoor PCB, it did not fault out.
So with my gauges connected where the HP and LP switches are located I found the unit to be running at 80PSI on the suction line and 320PSI on the discharge. Rather high for my liking.
Both Condenser fans are running and the coil is clean. The R/A filter is clean as well as the indoor coil. There are no duct restrictions.
It has a fixed oriface with capillary on the indoor unit.
The owner has lived here for 3 years and says no one has ever worked on it.
Any one got any idea's? Or should it be reclaimed and tested for non-condensibles or overcharged?
Thanks in advance!
